A trap and a method for using a trap

Abstract

A trap for exterminating pests, preferably rats in sewers, said trap comprising: a trap housing and a bait mechanism. The trap also has a trigger mechanism capable of detecting the presence of a rat and releasing a killer mechanism when the rat is within the total range of the killer mechanism; and a trapper mechanism capable of detaining an animal. The trap may also convey a killed animal from a first position, in which discharge of the killed animal will not entail that it is conveyed away by water running through the sewer, to a second position, in which discharge of the killed rat will entail that it is conveyed away by water running through the sewer.

1 . A trap for exterminating animals causing damage, preferably rats in sewers, said trap comprising:
 a trap housing;   a bait mechanism;   a trigger mechanism capable of detecting the presence of a rat and releasing a killer mechanism when the rat is within the total range of the killer mechanism;   a trapper mechanism capable of detaining a rat;   a conveyor mechanism capable of transporting a killed rat from a first position, in which discharge of the killed rat will not entail that it is conveyed away by water running through the sewer, to a second position, in which discharge of the killed rat will entail that it is conveyed away by water running through the sewer;   a programmable control unit connected to and adapted to: the trigger mechanism, the killer mechanism, the trapper mechanism, and the discharge mechanism to the effect that the control mechanism activates the trapper mechanism such that it detains a rat when the latter is detected by the trigger mechanism within the total range of the killer mechanism, said control unit also activating the killer mechanism and the conveyor mechanism to the effect that trapped and killed rats are conveyed from the first position to the second position;   a unit for activating the trap.   
     
     
         2 . A trap according to  claim 1 , wherein the trap housing is configured cylindrically, and that the trapper mechanism of the trap sits in an end portion of the trap housing. 
     
     
         3 . A trap according to  claim 1 , wherein the trapper mechanism can discharge the rat when it is in the first position and in the second position. 
     
     
         4 . A trap according to  claim 1 , wherein the trapper mechanism can discharge the rat when it is any position between the first position and the second position. 
     
     
         5 . A trap according to  claim 1 , wherein the conveyor mechanism of the trap comprises a hinge mechanism around which the trap can pivot, said hinge mechanism being adapted to be such that pivoting of the trap entails that a trapped rat is moved from first position to second position. 
     
     
         6 . A trap according to  claim 2 , wherein, the trap's conveyor mechanism comprises a hinge mechanism deployed at that end portion of the trap housing which is opposite the trapper mechanism. 
     
     
         7 . A trap according to  claim 1 , wherein the conveyor mechanism comprises a telescopic mechanism capable of advancing the trapper mechanism such that it is moved from first position to second position. 
     
     
         8 . A trap according to  claim 1 , wherein the conveyor mechanism comprises a hinge mechanism and a telescope mechanism, and that they cooperate to move the trapper mechanism such that it is moved from first position to second position. 
     
     
         9 . A trap according to  claim 1 , wherein the transport mechanism comprises a hinge mechanism and a telescopic mechanism that are capable of moving the trapper mechanism independently of each other. 
     
     
         10 . A trap according to  claim 1 , wherein the killer mechanism also serves as trapper part. 
     
     
         11 . A method for exterminating sewer rats by means of a trap according to  claim 1 , said method comprising the following actions and measures:
 deployment of the trap in a first area of a sewer where the water does not have its natural course through the sewer;   adjustment of conveyor mechanism such that it is capable of conveying a rat from a first area of the sewer without water to another area of the sewer, said second area of the sewer being located such that discharge of a rat means that the rat is discharged in a part of a sewer pipe through which water flows and is hence flushed away by the water;   activation of the trap, whereby the killer mechanism, trigger mechanism, holder mechanism, and conveyor mechanism are activated whereby the trap is able to detect, kill and detain a rat in the first area of the sewer;   activation of the bait mechanism;   killing and detention of the rat;   movement of the rat from first area to second area;   discharge of the rat in the second area of the sewer;   activation of the trap.   
     
     
         12 . A trap according to  claim 2 , wherein the trapper mechanism can discharge the rat when it is in the first position and in the second position. 
     
     
         13 . A trap according to  claim 2 , wherein the trapper mechanism can discharge the rat when it is any position between the first position and the second position. 
     
     
         14 . A trap according to  claim 2 , wherein the conveyor mechanism of the trap comprises a hinge mechanism around which the trap can pivot, said hinge mechanism being adapted to be such that pivoting of the trap entails that a trapped rat is moved from first position to second position. 
     
     
         15 . A trap according to  claim 3 , wherein, the trap's conveyor mechanism comprises a hinge mechanism deployed at that end portion of the trap housing which is opposite the trapper mechanism. 
     
     
         16 . A trap according to  claim 2 , wherein the conveyor mechanism comprises a telescopic mechanism capable of advancing the trapper mechanism such that it is moved from first position to second position. 
     
     
         17 . A trap according to  claim 2 , wherein the conveyor mechanism comprises a hinge mechanism and a telescope mechanism, and that they cooperate to move the trapper mechanism such that it is moved from first position to second position. 
     
     
         18 . A trap according to  claim 2 , wherein the transport mechanism comprises a hinge mechanism and a telescopic mechanism that are capable of moving the trapper mechanism independently of each other. 
     
     
         19 . A trap according to  claim 2 , wherein the killer mechanism also serves as trapper part. 
     
     
         20 . A method for exterminating sewer rats by means of a trap according to  claim 2 , said method comprising the following actions and measures:
 deployment of the trap in a first area of a sewer where the water does not have its natural course through the sewer;   adjustment of conveyor mechanism such that it is capable of conveying a rat from a first area of the sewer without water to another area of the sewer, said second area of the sewer being located such that discharge of a rat means that the rat is discharged in a part of a sewer pipe through which water flows and is hence flushed away by the water;   activation of the trap, whereby the killer mechanism, trigger mechanism, holder mechanism, and conveyor mechanism are activated whereby the trap is able to detect, kill and detain a rat in the first area of the sewer;   activation of the bait mechanism;   killing and detention of the rat;   movement of the rat from first area to second area;   discharge of the rat in the second area of the sewer;   activation of the trap.
